BACKGROUND OF THE INVENTION

Computerized online mapping systems are becoming increasingly popular for mapping locations requested by a user. These Internet websites for mapping are useful for mapping a requested location, for example. These websites typically allow a user to input a query of a requested location so that a map associated with the requested location may be provided to the user.

As another example, these mapping websites facilitate travel planning. The user may enter a start point and an end point for travel, which are then used to calculate and provide travel directions to the user. Travel directions may include the routes to take and an estimated time for arrival.

These types of mapping systems require a user interface for a user to enter in a request for a map, and an interface where the map is provided for displaying to the requesting user.

A general user interface 100 for a mapping website is illustrated in FIG. 1. The user may enter in the address of the desired location as a request in an entry box 100. As shown, a user has entered a desired location of 425 Market St., San Francisco, Calif. 94105. After entering the desired location to be mapped, as shown in FIG. 1, the user then requests a map (typically from a remote server) by selecting a button for submitting the request to a map server 104. A map image is then typically generated at the remote server, transmitted to the user's computing device, and eventually displayed on the web browser user interface in a map display web page 106.

The map image may be composed of map tiles that are pre-generated. Typically, pre-generated map tiles fall into the categories of: vector/text tiles for roads/names/POI; rastor images (e.g., satellite images); and transparent overlays (e.g., roads over a satellite image).

In a mapping system, generally the same type, or category, of pre-generated map tiles are used. For example, the same vector style is used for maps of San Francisco and maps of New York or London. In this way, the initial generation of a map is simpler for the presentation of information such as roads.

However, a user may often want more information displayed in the map than the information of the pre-generated map tile. For example, if the user is interested in viewing more information, such as walking paths, in the requested map location, the desired information may no be available. Furthermore, if a map tile is pre-generated to include other desired information, the contextual focus of the map becomes confusing and difficult to comprehend.

Therefore, it is important to recognize different users may want to view maps for different purposes, thus requiring other significant information in a map associated with the desired purpose.

For example, a user who drives a car for commuting may care about road directions, road classes, and road restrictions. In another example, a user who enjoys walking around town may desire information associated with points of interest, walking paths, places to sit, places to eat, etc.

Therefore, methods and systems for providing customized map tiles are desired.

DETAILED DESCRIPTION OF THE INVENTION

The following description is presented to enable any person of ordinary skill in the art to make and use the invention. Descriptions of specific materials, techniques, and applications are provided only as examples. Various modifications to the examples described herein will be readily apparent to those of ordinary skill in the art, and the general principles defined herein may be applied to other examples and applications without departing from the spirit and scope of the invention. Thus, the present invention is not intended to be limited to the examples described and shown.

According to embodiments of the invention, map tiles for specific regions of interest are provided. This provides an extended set of map tile styles customized for specific usage cases, such as map tiles that show specific features of interests. These customized map tiles are described as Region of Interest (ROI) map tiles.

As opposed to overlaying the features of interest on top of a base map tile that may already show many other features or information, some of which may be extraneous information for a user with a specific interest, according to embodiments of the invention, a separate set of map tiles (ROI map tiles) showing the features of interest are generated. In this way, the ROI map tiles can be swapped for the base tiles corresponding to the same location.

A bounding latitude/longitude box of a ROI map tile is already known. Similarly, the zoom ranges used in a mapping system are also known. This allows the ROI map tiles to be pre-generated in any pre-determined ROI style.

In contrast to map systems that overlay information over base map tiles, because the bounding latitude/longitude box of the ROI map tiles are known, the system can derive the map portion associated with each ROI map tile. Therefore, if the requested map portion includes a ROI map tile, then it can be provided to the user. The front end server may periodically query the back end server to determine if ROI map tiles are associated with the requested map portion.

By customizing maps in this way, source data needed for generation of map tiles does not need to be communicated to the client browser. For example, latitude/longitude information is not known to the browser.

This makes it possible for browsers of different complexities to be able to display customized maps to users, e.g., displaying a customized map to a user on a mobile phone browser or at a desktop computer browser.

The pre-generation of tiles at a server also allows for the ease of adding other map tile styles to the customization options. The whole map system platform would not have to be modified if local markets wanted to add in tile styles more appropriate to local usage situations, for example.

Several styles of ROI map tiles are possible. An example of a ROI style is a tourist view, which may emphasize landmarks, hotels, and restaurants. Another possible ROI style is a commuter view, which may emphasize public transportation options available in the requested map portion.

FIG. 2 illustrates a method 200 for customizing a map with ROI map tiles, according to embodiments of the invention. The method includes receiving a query for a portion of a map from a user 202. It is determined if a predetermined region of interest map tile is included in the portion of the map indicated in the query 204. The predetermined ROI map tile indicates information associated with a category. The category may be determined by a desired map style.

A map style may be tourist views, for example. The tourist style ROI map tiles may include information such as hotels, restaurants, tourist attractions, and public transportation information, for example.

The predetermined ROI map tile is provided for displaying to a user 206. The ROI map tile is provided in place of a base map tile in generating the requested portion of the map.

FIG. 3 illustrates a system for customizing maps according to embodiments of the invention. A user 302 may be viewing map provided by the map display 304. The requested portion of the map changes as the user 302 changes the portion of map they are viewing. For example, the user 302 may wish to view another area of the map that is displayed and scroll to the different position, thereby requesting a different portion of a map.

As the user 302 scrolls around a map, refresh and movement events are generated. The generated refresh and movement events initiate a map request query to a movement event processor 312. In other words, as the user 302 navigates navigation around the map, at certain intervals, a map request query is sent to a the movement event processor 312 to see if any ROI map tiles have been generated for the requested portion of the map. In embodiments of the invention, the map portion query is generated in response to a movement event of 0.1 degrees.

The movement event processor includes a ROI detector 314. The ROI detector 314 determines if any ROI map tiles are associated with the requested map portion. The requested map portion based on the navigation of the map by the user 302 is compared with the available pre-generated ROI map tiles indicated by the ROI list 320. The ROI list may include information such as bounding latitude/longitude box, zoom ranges, and associated URLs for each ROI map tile.

If the requested portion includes available ROI map tiles, the user 302 may be given the option to confirm that the ROI map tiles should be used to generate the map. The option for the user 302 to confirm the ROI map tiles may be provided to the user 302 in a pop-up window, for example.

There may be one or more ROI map tiles styles associated with a requested map portion. If the user 302 confirms the use of a ROI map tile style, then for the region of the portion of the map where ROI map tiles of the selected ROI map tile style are available are provided for display to the user 302 instead of the base map tiles. The ROI selector 318 selects the appropriate ROI map tiles.

The local Tile Server list 310 is updated with the selected ROI map tiles to indicate which tile server is associated with the determine ROI map tiles. This way, when the map tile layout needs to be regenerated, the right tile servers are selected and the necessary tile servers are enabled for the selected ROI map tiles.

There may be a plurality of tile servers for providing ROI map tiles, such as tile server 324 and tile server 326. The tile servers 324 and 326 host ROI map tiles in separately addressable locations.

The map is generated with base map tiles stored in the universal tile server 322, and any ROI map tiles stored in tile servers 324 or 326, for example.

FIG. 4 illustrates a map 400 of Sydney, Australia indicating regions of the map where pre-generated ROI map tiles are available, according to embodiments of the invention. In region 402, there are available ROI map tiles of a style that include pedestrian interests. Pedestrian interests that may be indicated on this style of ROI map tile may be indications of walking paths, hiking trails, places to sit, and interesting landmarks. In another example, region 404 may include ROI map tiles for a style for tourists. The features included in these ROI map tiles directed towards tourist, may include indications of hotels, restaurants, museums, public transportation indicators, and tourist destinations

As another example according to embodiments of the invention, a topological map 500 of Sydney is illustrated in FIG. 5. A user interested in hiking may have selected a ROI map tile style that indicates the topology of a region so that the expected difficulty of a particular hiking trail is illustrated on the map.
